Re: Successful navigation swap into a non Nav CTS

Got all my stuff in today. Came in two huge heavy boxes and I was baffled as to why. Looks like they sent me the entire interior main body harness for the car! Every radio connection is there, with all harnesses between the radio and screen, instrument panel, what even looks like the fog light wiring, USB/AUX harness, EVERYTHING out of the interior.

Because of having access to my dad's body shop I can easily just have the main harness swapped...or should I just cut the connectors and follow the wiring directions? Still haven't gotten a soldering iron for that part.

Swapping the main harness would probably require taking the interior apart and taking the dash board out and apart. This will most likely lead to squeaks and rattles once it's are back together later.

Re: Successful navigation swap into a non Nav CTS

Yeah it's a big job that I don't think I want done. Although there is a small rattle I'd like to get taken care of, this will not be worth that. I'm just a bit nervous about cutting the wires at the connectors I guess!

This might be a dumb question, but how do I remove the wires from the connectors? Do they pull straight out without tearing or is there a trick?

Just dropped my radio off for unlocking, can't wait to get it back in and start working! In the meantime, I installed all the CTS-V pieces I received. It looks nice! The process took almost 2 hours but that was because I had to swap the screen, all the buttons, and ashtray over on the surround. If someone were to order a surround with all the same buttons/features the whole process would be very short. I purchased the shifter and steering wheel to go with it, they should come in sometime this week.

You have to remove the safety clip from the connector to remove the pins. Yes it is a trick.

1968vert, in the info you sent me, you wrote that the display connectors X1 and X2 need their orange wires spliced. I understand that part, but what about the rest of the wires?? I looked at the harnesses and each connector has multiple wires and not just a single orange wire. Surely I don't leave those all cut and not connected.

The wire diagram shows where all the wires go. Pretty much all those wires for the display will have to be added, either by making a harness with your new pigtails or swapping the new harness over. You have to follow the diagram.

Re: Successful navigation swap into a non Nav CTS

Great. Lol. I didn't even think about that part. I guess I assumed all the wiring would be present and we would only be adding what you highlighted in the PDF.

Just to see if I am reading the diagram correctly, let's do an example. Display X2 pin 4 goes to radio X4 pin 4? And display X2 pin 5 goes to radio X4 pin 5? I am just following the lines straight down so I am assuming that's correct but would just like to confirm.

Or how hard would it be to swap that part of the harness over? I have the whole thing and can unwrap it if needed.

The display has a total of 3 connectors: x1, x2, x3. X1 looks like it has a total of 7 wires in the diagram. Pin 1 (orange) gets splice with the power wire coming out of the radio (pin 44 i believe). Pin 2 (blk/wht) goes to ground. Pin 4 (wht) goes to pin 43 in the radio. Pin 7, ,6 ,and 8 get wrapped in shielding and go to the radios x4 pin 9, 19, 8. The X2 from the display has 5 wires: Pin 1 (orange) goes to power. Pin 2 ground. Pin 4 an 5 (ye and ye) goes to pin 4 and 13 in the radios x4. pin 3 (wht) gets spliced with the wht out of x1 (pin 3).

Re: Successful navigation swap into a non Nav CTS

My unit came with out the pigtails. I've tried searching for any info on where to get them or part numbers. Any one know any of the harness' part numbers, where to get them or how I can find any? just sent the hard drive off to get unlocked and would like to get the install started when it comes back. thank you for this post as it has been something I've wanted to try for a long time.. Lots of good info here. ESP 1968VERT. thank you. I did a how to on installing a back up cam to keep the factory set up. i know the it's not easy keeping the post going.

Hey bojangles your best bet would be junk yard or search ebay. It will be hard but should be able to find something, the dealer only carry that usb type wire that connect the hdd to screen and it cost over $400. So check with junk yards and good luck.

I called several junk yards but no one keeps or sells harness' let alone the pigtails. Fleabay has been a bust too. crazy to think people that work and install this shit at shops refuse to do it but it can be done by regular people. RUDEBOYSPI seems like you came quite a way to, I've been follow this forum taking notes on what and where to wire. as well as the manual I have. only thing stopping me is getting the harness'. sucks balls. thanks for the responses so far btw

Re: Successful navigation swap into a non Nav CTS

Bojangle, when I bought my nav setup they sent me an enormous harness. From looking at it, there is no small harness for behind the radio. Everything is wired into the big harness they sent me, which when I ran the part number ran for $700. So you will definitely just have to find the pigtails or find that main interior harness but it will be expensive. I got lucky that they sent me that for no extra charge.
